Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid engine. An object of the present invention is to provide a power-saving differential fluid prime mover.

[0002]

[Prior Art] At present, there is no prime mover that operates with pressure as the main input, and there is no complete product.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a low-input fluid power engine in which the input from a pressure source pump is mainly pressure only and the inflow of fluid is minimized. The problem lies in the discovery of the structural principle of motion with pressure as the primary input.

[0004]

First, it has been discovered that the relative movement of the cylinder pistons provided at the same time makes it possible to generate a circulating flow of the internal fluid during equal pressurization, thereby enabling a propulsion motion with pressure as an input. Has been done.
Next, when relative movement of the piston occurs, a cylinder arrangement is adopted in which both ends of the balance attached to the crankshaft or the like are pressed against each other, and the eccentric position of the balance is contact-pressed to a fixed fulcrum,
This is due to the development of a structure that makes the piston move relative to each other.

[0005]

[Function] When the fulcrum axis of the balance is at the center, even if both ends are pressurized by the pressurizing cylinder piston, no motion occurs evenly. By setting the fixed fulcrum at the eccentric position, a propulsion motion is generated while tilting by the action of the balancer at equal pressure.

However, when the fixed fulcrum of the balance is not at the center,
The movement dimensions of both ends of the balance are not equal.Therefore, the width of the balance is enlarged as an inclined surface, and the contact position with the fixed fulcrum is moved according to the sector movement of the eccentric shaft. By interaction. The first feature is that the same relative movement stroke of the attached cylinder piston can be maintained.

[0007] The relative movement of the cylinder piston, which presses both ends of the balance attached to the eccentric crank in parallel, causes the piston on the propulsion side to move forward and the piston on the discharge side to retreat by the same amount. Equal volume circulation is possible. Therefore, it does not require the inflow of fluid from the pump, and the cylinder moves continuously to the terminal by inputting only pressure. The most important feature of the present invention is the generation of motion due to the circulation of the iso-pressurizing circuit.

[0008] However, as a feature of the equal pressurized recirculation motion, continuous motion is possible by inputting only during pressurization and during pressurization.
0% fluid injection is required. It can be said that it is 10% inflow, but if you repeatedly reduce and increase the pressure,
The labor-saving effect of the circulating motion with constant pressure input will not be realized.

As a countermeasure against the problem, 10
Percentage pressure reduction is released to the auxiliary cylinder, and the return injection is completed inside the cylinder by its own thrust just before the next pressurization. It is possible in about. It is also possible to use a low-pressure pump to inject the liquid first and then switch to a high-pressure pump at startup. With the addition of the above mechanism, the practicality of the pressurized circulating engine, such as energy saving, is established.

[0010]

[Embodiment] Although there are various mechanisms of the embodiment,
The first embodiment of FIG. 1 will be described. Fig. 1 This is a linear reciprocating motion engine, and is in the state of moving to the left indicated by 24. First, the hydraulic pump 2 is driven, and the advance valve 3 is turned on.
If N is set, 9 and 10 cylinders are equally pressurized through 5 pressurization circuits, and both generate thrust in the 22 direction. FIG.
It is a schematic diagram of the state at the time of startup of the first embodiment.

[0011] Both ends of the cylinder pistons 9 and 10 and the balance of 11 are pressurized and pressed against 15 fixed supports on the left side. Due to the fixed fulcrum of the pressing position of the balance and one-third of the total length of the balance, the mutual thrust ratio is 2: 1 even though it is the same thrust due to the action of the roller.

Therefore, the piston 9 moves in the direction of the piston 24 with a double thrust and moves in the opposite direction to the piston 10. Passes through the circulation circuit of internal fluid 7 compressed by the discharge cylinder piston 10 and fills the propulsion cylinder 9 so that it does not need to flow in from the pump and continues to move by inputting only pressure. .

[0013] Because the input consumption of pressure only is extremely small, a low input motion engine is established. This is a 13-wheel crankwheel that converts the linear thrust of the cylinder into an output motion with eccentric shaft-fan motion. Due to the fan-shaped rotation of the eccentric shaft of 12 and the oblique shape of the balance and the shape of the fixed fulcrum, 9,
The relative movement of the same dimensions of 10 cylinder pistons is possible. Thirteen gears are output from the 90-degree rotation output from the 12 eccentric shafts, and in the case of rotary motion output, transmitted to the 21 rotation output shafts by the 19 cranks and 20 crank wheels.

When the vehicle reaches the left-hand terminal, it is detected by a cam, a limit switch, etc., and by switching to 4 retreat valves, the wheel 13 is reversed by 90 degrees and returned to the right-hand terminal by the same principle of motion. Return to the right-hand terminal to return to 3
By turning on the advance valve of, the cycle of reciprocating motion is continued.

However, since the discharge amount of the fluid required for the pressure drop at the time of switching the pressurization is one-tenth of the volume, it is released into the 34 or 35 auxiliary cylinders whose volumes are matched. In the non-pressurized movement, the mechanism turns on the 39 electromagnetic clutch, opens the auxiliary valve, and returns and injects it into the cylinder by self-thrust. In FIG.
In this state, the injection of auxiliary cylinder is completed, the auxiliary valve of 36 is closed and the auxiliary valve of 36 is closed.

In the state where the release injection is completed with the auxiliary cylinder 35 and the clutch OF 39,
Turn on 39 at the same time as starting, and start injection into circuit 8 by the motion thrust. The state shown in FIG. 4 is the arrangement reaching the left end indicated by 24 in the first embodiment, and the auxiliary cylinder is in the state of waiting for pressurization of the 6 backward pressurizing circuit by performing the operation opposite to the operation described in FIG. is.

As an effect of the auxiliary cylinder, the rise input of 10% of the cylinder capacity can be made to about 2%, and the practicality of this engine is established. In the embodiment, a spring is used as the back pressure of the auxiliary cylinder, but the use of a pneumatic constant pressure valve is effective. The above is the description of the structure and operation principle of the first embodiment.

A second embodiment shown in FIG. 2 will be described.
The gear arrangement of FIG. 2 is the same principle as that of the first embodiment, but the crank eccentric wheel is replaced with an eccentric gear with a one-way rotating cam clutch, and the eccentric gears are plural, and 5 and 29 are alternated. It is characterized by pressurization and continuous one-way rotation. Use of fixed fulcrum bearings is also effective.

A manufacturing method in which a balance is mounted on a roller, an internal gear type eccentric shaft, or the like is also possible, and a method in which a pressure intensifier is used in an equalizing circuit is also effective. The speed can be controlled by adjusting the flow rate of the circulation circuit. The above is an explanation of the structure and the principle of movement according to each embodiment. The addition of a small pump, accumulator, dynamo, battery, etc. makes it possible to use it as an independent engine. In addition, a motion stroke adjustment method by arranging multiple main cylinders in series is also possible.

According to the principle of the differential motion structure of the present invention,
Since the main input is the efficiency of the fluid engine, the pressure is very large, and the theoretical input efficiency is about 1 compared to the conventional hydraulic engine.
Since it is 0 times or more, various uses are possible. It is an important invention that contributes to energy saving problems as a reciprocating engine for presses, lifts, injection molding machines, etc., as well as a propulsion engine for vehicles, ships, etc., and a driving motor for generators, as applications of differential static pressure circulating engines.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid engine. An object of the present invention is to provide a fluid differential engine that moves with pressure as a main input.

[0002]

2. Description of the Related Art At the present time, advanced finished products of pressure input differential engines are not provided.

[0003]

[Problems to be solved by the invention] The problem of the circulating differential engine is how to efficiently reduce the reverse propulsion generated in the propulsion cylinder.

[0004]

Means for Solving the Problems In a method of counteracting a reverse thrust generated in a propulsion cylinder by applying a back pressure, the pressure is sequentially reduced stepwise, and a series of back pressure is arranged. It has been confirmed that the output efficiency of the propulsion cylinder increases in proportion to the number of descending pressure stages.

[0005]

[Function] In the ratio of the back pressure drop pressure, it is appropriate to reduce the pressure by half, but it is also effective to add cylinders and subdivide the pressure. It is determined by the output of the propulsion cylinder, the head pressure of the propulsion cylinder and the head drop of the back pressure in the final stage. In accordance with the movement of the propulsion cylinder piston, the fluid inside the back pressure cylinder and the equal pressure are sequentially circulated to the front cylinder.

[0006] Due to the mutual capacity of the cylinders, a circulating motion with a main input of pressurized pressure is established without the need for fluid inflow from the circulating pump. The exercise and structure will be described with reference to the embodiment of FIG.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a linear reciprocating type differential engine has a basic structure.
The series arrangement of cylinders is a circulating series structure through 18, 19 balances. FIG. 1 shows a state where the forward rack shaft shown in FIG. 20 is moving in the forward direction 24.
When the pumps 2, 12, and 13 are driven first, 9 and 10 are obtained.
Is constantly pressurized.

[0008] Circuit 9 applies equal pressure to the back pressure part of the cylinders 15 and 16. Pressurizing pressure Main circuit propulsion pressure and 1
Equivalent to 00 percent. There is a guarantee of propulsion pressure for 14 reasons. The 10 circuits resist thrust of the propulsion cylinder as 25% pressure in the last stage, and at the same time counteract 50% of 17 cylinders. The output of the 11 motors is 0, regardless of the cylinder volume and pressure.
It is possible with a small capacity of about 5 horsepower.

Next, if the forward valve 5 is turned on and the forward pressure circuit 7 is pressurized, cylinders 14 and 15 will be pressurized, and thrust will be generated in the direction of 22 each. At the same time, the reversing valve of 6 is OF, but the pressure switch of 3 and the stop valve of 4 in the circuit of 8 make the 50
Present as a percent residual pressure.

Therefore, thirteen thrust cylinder thrusts, 1
The back pressure cylinder of 5 is guaranteed by the pressurized pressure of 100%, and the 16 cylinders have a pressure of 50% against 9 normal pressure of 9%. In addition, thirteen cylinders and eight circuits reduce thrust by 50% pressure and 25% normal pressure.

In the last 10 circuits, the thrust of 14 thrust cylinders at 100% and the thrust of 25% at normal pressure is opposed to the thrust at normal pressure of 25%, and the thrust is advanced by 75% of theoretical thrust. It does not require the inflow of water and maintains forward movement with the pressurized pressure as the main input.

When the vehicle arrives at the forward terminal, the position is detected by a limit switch or the like, the circuit 7 is depressed to 50% as an OF, and the circuit 8 is pressurized. 17 becomes high pressure and shifts to retreat propulsion. When reaching the retreat terminal, the circuit of 8 is depressurized and the forward movement is started by pressurizing the circuit of 7 again, and the cycle is continued by repeating the above procedure.

By the alternating movement of the rack shafts of the output shafts 20 and 21, the rotation is taken out by the one-way rotating cam clutch 23. In FIG. 1, the circulation circuit provided in parallel with each pressure circuit is omitted. The above is an explanation of the principle and structure of movement. However, it is necessary to solve the problem of labor saving of input at startup. It is necessary to discharge 10% of the volume of fluid required for decompression when the piston is stopped in the normal hydraulic circuit.

In the present engine, since the residual pressure is 50%, about half discharge is possible and only 5% inflow is required. Even though it consumes 5%, an instantaneous high pressure input consumes a huge amount. Therefore,
By filling the inside of the cylinder with a low pressure that does not apply a load at the beginning and pressurizing the high pressure when the injection is completed, the input at startup can be extremely small due to the characteristics of the fluid pressurization.

In addition to the method of using the variable pressure pump of the embodiment, there are a method of installing a low-pressure and high-pressure two-stage pump, and a method of installing a cylinder dedicated to absorbing and discharging a depressurizing fluid. Thus, this engine is established as a low input fluid engine.
It is also possible to use a manufacturing method in which gears, cranks, etc. are used as the point of application of the piston. It is also possible to manufacture a countermeasure by interposing a balance, gear, crank, etc. for each cylinder.
It is also possible to replace residual pressure with pump pressure. In addition, a multi-stage pressure reduction method with additional back pressure cylinders and gears is also possible.

The cylinder stroke and volume can be selected, and the speed can be controlled by adjusting the flow rate of the circulation circuit. In addition, a small pump, accumulator, dynamo, battery, etc., can be used as an independent engine.

According to the present invention, the differential recirculating engine of the present invention uses the pressurized pressure as the main input, so that the input efficiency can be several times higher than that of the conventional hydraulic engine. This is an important invention that contributes to energy conservation and the environment as a driving engine for propulsion engines for vehicles, ships, etc., as well as reciprocating engines for aircraft and civil engineering machines.
